A11: Feedback control for quantum information processing

Maintaining coherence in the face of interactions with the environment is essential for reliably manipulat-ing quantum states and thus quantum information processing. One prominent strategy towards this goalrelies on the measurement of error syndromes and subsequent active quantum error correction. Sucherror correcting codes typically rely on projective syndrome readout. In practice, such projective measure-ments may be too difficult or too time consuming. In this project, we explore feedback-based strategiestowards this goal which use weak rather than projective measurements, with a focus on topologicalquantum computation and the underlying adiabatic quantum dynamics.
